| Outline of Final Research Achievements |
Fiber lasers have high performances. Therefore, the fiber lasers are applied in manufacturing fields. We developed the high power fiber laser without using the double-clad fiber technology. Five fiber laser modules (FLMs) were combined to single fiber laser cavity by our coherent-cavity-combining technologies.
In this research, we achieved the development of below indispensable technology concerning the coherent-cavity-combining systems. High precision fiber length control system that has resolution of 20 nm. The combining methods of arbitrary number of fiber laser module. Finally, we achieved 5.09 W laser output power from a single single mode fiber by combined five FLMs.
